## What it is
JupyterLab is an extensible, web-based interactive computing environment for authoring computational notebooks, with support for code consoles, terminals, text editors, and rich outputs. It is the next-generation interface for Project Jupyter and can be extended via prebuilt or source extensions distributed through PyPI, conda, and npm.

## Use cases
- write and run jupyter notebooks in the browser
- explore and visualize datasets interactively
- prototype python code with inline outputs and charts
- run terminals and text editors alongside notebooks
- build a reproducible data science workflow
- extend the notebook UI with custom extensions
- teach programming with shareable notebook documents

## When to choose
- you need a full-featured notebook authoring and editing environment
- you want a customizable, extensible interface beyond classic Jupyter Notebook
- you work with data science, machine learning, or interactive computing across many kernels
- you need real-time collaboration, debugging, and workspaces in a notebook tool

## When to avoid
- you only need a lightweight single-notebook interface (Jupyter Notebook may suffice)
- you need a traditional script-based IDE without notebook semantics
- you require a fully offline desktop app without a server (though JupyterLab Desktop exists)
- you want a minimal editor for non-notebook code files

## Facets
